<p>Worksheet 16.2 Chapter 16: Neurobiology and behaviour – command terms to master Draw Represent by means of pencil lines. Label Add labels to a diagram. Annotate Add brief notes to a diagram or graph.</p><p>Examples Assessment statement E.1.3 Draw and label a reflex arc for a pain withdrawal reflex, including the spinal cord and its spinal nerves, relay neurone and effector. Assessment statement E.2.2 Label a diagram of the structure of the human eye. Assessment statement E.2.3 Annotate a diagram of the retina to show the cell types and the direction in which the light moves.</p><p>Author’s comment Practise how to draw and label a reflex arc for a pain withdrawal reflex (including receptor cell, sensory neurone, relay neurone, motor neurone and effector). Learn how the parts interact while you are learning to draw them. Also include the white and grey matter of the spinal cord, and the ventral and dorsal roots of the spinal nerve. Be able to show the position of the cell body of each neurone in your drawing. Make your drawing at least the size of one-third of a page. Draw and label in pencil and print all labels. Be careful when you draw a line to label a part. Learn to label the following diagrams. Use the pictures in your text. Cover the labels and practise writing them. It is typical for one of these to be on the Paper 3 exam. They are easy to learn if you practise.  A diagram of the human eye including: sclera, cornea, conjunctiva, eyelid, choroid, aqueous humor, pupil, lens, iris, vitreous humor, retina, fovea, optic nerve, blind spot.  A diagram of the ear including: pinna, eardrum, bones of the middle ear, oval window, round window, semicircular canals, auditory nerve and cochlea. Explain how sound is heard by using the eardrum, bones of the middle ear, oval and round windows and the hair cells of the cochlea.  A diagram of the brain with the following; medulla oblongata, cerebellum, hypothalamus, pituitary gland and cerebral hemispheres. Learn the functions of each part. Annotate a diagram of the retina. This means to label the rod cells, cone cells, bipolar neurones, ganglion cells, and show the direction in which light moves. You must also be able to compare rod cells and cone cells in a comparison chart.</p><p>© Pearson Education Ltd 2010.
